Assembly of the HighStep Rail

Connecting to different buildings and structures

HighStep offers multiple adapters to connect with different kind of buildings or structures, such as towers, pylons, masts, poles, shafts or storefronts.

Tubular profile adapter

Angle profile adapter

Round-mast adapters

Ladder adapter

Tubular profile adapter for connection to tubular profiles on lattice towers. A range of sizes between 60 and 220 mm cover the entire range of different diameters.

Angle profile adapters for connection to an L-profile on a lattice tower. Typical bolt diameters are M12, M16, M20, M24 and M27.

The round tower adapter is used if a diameter is too large for the tubular profile adapter. The spring bracket is held by an M16 bolt inserted into the adapter.

The ladder adapter enables the HighStep Rail to be attached to rectangular rungs of a ladder. The adapter envelops and clamps the rung. Drilling is not necessary.

Pre-assembly

The pre-assembly takes place in two stages:

• Pre-assembly of the rail holding point and spring bracket sets

• Pre-assembly of the Rails

Pre-assembly of the connecting points

The HighStep Rail is attached to the supporting structure using both the rail holding point and the spring bracket sets. These two sets can be pre-assembled on the ground for each holding point. The example shown here is for a holding point on a lattice tower, which also requires the angle profile adapter.

Pre-assembly of the rails

A rail connection profile is attached to the top end of each Rail. This will later be used to connect two segments together.

Assembly

Step by step assembly sequence

The pre-assembled rail holding points are bolted to the transverse struts of the lattice tower. A good attachment point is where two transverse struts cross in the centre of the tower wall.

Assembly of subsequent rail segments and final work

Once the rail has been adequately secured, the erector can insert the HighStep devices into the rail, attach himself to them and climb up. When he comes to a place where a holding point is to be mounted, he rivets and bolts it while standing on the rail. When he reaches the top end of the mounted rail segment, the next rail to be assembled is pulled up with a rope hoist.

The last rail segment has to be cut to length before it is mounted. After the last segment has been riveted in place, the entire rail has been completely mounted.
